I own a Portable Gamer PC 17 "that heats enormously up to 70 ° C in 2 hours of use (without play), imagine when I play with high graphics? Thereby lowering the cooler temperature of around 20 ° C! Failure to correctly place the 3 fans (HDD, CPU and GPU) is a brilliant idea. You can also change the fan speed. For my part, I think it does not make much noise compared to the NotePal U2 (of the same brand) I had before and my pc. I highly recommend it for people using his Laptop around 5 hours per day on average, the difference you can really see.
